Upon this is laid a thin disk of paper 01' any dcisircd packing 10. The cup 11 shouhlhc made of Fusilirnt nmtcrinl such as still and springy steel or tin pinto, and has n scrirs of arms 12 endin;: in dn'wmvnrdly hunt lcgs 13 having any desired l'nstcning mcans thereon to engage thc lmttlc head. As shown herein, 1 have PlUVltlNl an inwnrd lip 15, turned it 0r punched out (if the log 13. The tnp oi thc cap it has n dcpcnding nnnulnr head cr rib H, which scrvvs as n sharply defined contactsnrl'acc to i-ngagv the huttlc head and thipacking Ill, and also makes the cap stiff and prvvcnis ii disturtiun from bending the arms 12. 'lhcsc arms are flat, and are set at an an- ;:l to thc plane 0i thc top of thc cap and at such an nnglc to the lrgs 13 as to rvquirc the sprmnling of thc nng'lc and bonding oi the arms l2 as the cap is pushed down over the hvnd sprvnding the legs 13. It will he no tic-ed that thc lcgs 13 are curved circumfercntinlly to the bottle, so that in spreading thcy will not bend along their length.

As shown in Figurc 2, anyflnt surface B is pressed down 011 the cap, cngsgin the outer ends of the arms 12, and by the slhpc 0f the hand spreading them laterally, bending downward the arms 13 by the resistance of the head on the head 14, compressing the packing it) thereon, when the lips 15 will snap over the ledge i) and lock the cap in place (in the bottle. In this condition the effort cf the legs 13 to regain the normal angle with the arms 12 will keep the lips 15 snfcl cngngod under thc lcdgc S and this tcn ency tngcthcrwith thc cilurt 0f the arms 12 to rcgnin nurmnl angle with the top of the cap, will cxcrt it very trong, constant and resilient or inkling prcssurc on the packing, scalin thn mlllv against inside pressure of thc liquid cr gas. tfi'vc l igurc 3.)

Thu rlusnrc may he opcnod by releasing the logs 13 in an) dcsircd way; hut I find it cunvcnicntftu do this by prcssing downward un the cap n tcul as shown in Figure 6, which is made at a conical cup shape and enga ing the outer rim ol the cap at the jnnet ure ol the arms I23 and legs til spreads the angle between them, at the same time releasing the lips 15 as shown.

Of course it will be understood that the lips for engaging the ledge 9 may be bent up inward l'or engagement alter the cap has been pressed down on the head, or the leg 13 may be bent in an other suitable manner to engage, without departing from the spirit of my invention. The various advantages of the device will be readily apparent to those l'amiliar with the art to which the invention appertains.

llaving thus described my invention and its use, what 1 claim as new, and desire to secure by Letters Patent, is the following:

1. A bottle closure comprising a body for covering the bottle opening, resilient flat arms on the body at an angle thereto and adapted to bend down, rigid legs on the arms for embracing and engaging the bottle head when the arms are depressed.substantially as described.

2. The combination with a bottle head having a retaining ledge, of a closing cap comprising a body with rigid circumierence, flat spring arms outside the eircuinference set at an angle with the body, depending legs on thearms embracing the bottle head and having catches to engage the ledge, the diameters of the head and cap being such that the angle between the arms and legs is spread when the cap is forced down over the head substantially as and for the purpose described.

3. The combination with a rounded bottle head having a circuinferential ledge 9, of a metallic stopper cap comprising a disk 11, angular resilient llat arms 12 with depending rigid legs 13 and catch lips 15 adapted to engage the ledge.

4. In a bottle closure a disk having upwardly slanting flat arms capable of bending, downturned rigid legs to embrace a bottle head, and means to leek the legs on the head, substantially as described.

5. The combination with a rounded bottle head having a Hat top seating surface and an outside annular ledge, of a closing disk having an annular ridge engaging the head, and angularly disposed llat arms with depending legs adapted to engage said ledge and press the ridge downward, the dimensions being such that the legs on the arms are circumferentially spread in springing over the ledge, substantially as described.

6. The combination with a bottle having a retaining ledge and a rounded head, of a cap having angularlv disposed arms with legs thereon embracing the head, and retained thereon and exerting resilient pressure thereon. said arms being bent and adapted to ltt s H'ttttl by the rounded bottle head to retell-e I ie can when the latter is ushed dow n on Ilte bottle.

7. 'lhe combination with a bottle head having a. sloping outer surface and a retain ingl dge, oi a resilient cup with divided sides adapted to engage the head and snap over 1 he ledge, and adapted to be spread and released when said can is pressed down on the head beyond its elastic limit, substantially as de scribed.

8. lhe combination with a rounded bottle head having a retaining ledge, of a stopper cap having tlat. resilient arms with legs-thereon engaging the head, the angle between the said arms and legs being sharper than the curve of the head, whereby the legs are spread and released when the cap is pressed down upon the head beyond the elastic limit of the arms and legs.

9. A bottle closing cap having resilient engaging legs substantially as set l'orth, adapted to lock itself on the bottle head when the legs are pressed downward, and to be released by spreadingthe legs when pressed l'urtherdownward upon the bottle head, substantially as described.

it). A bottle closing cap comprising :1 [lat disk, 11, with an annular ridge, 14, and having upwardly bent arms 12, and downwardly bent legs 13 with catch spurs 15, arranged substantially as described.

11. A bottle closing cap having an annular ridge or bead 14 to engage a llat topped surface of a bottle, and resilient means in the cap for exerting pressure on the bead, substantially as described.

12. In a bottle closing cap a series of resilientl v-mounted legs for embracing the bottle head and having punched out lips 15 to engage the head, substantially as described.

13. The combination with a bottle head of rounded contour, of a (losing cap therefor having resilient members adapted to engage the head when the cap is pressed on, the members having bends adapted to be spread by further pressure down on the head, to thereby release the engaging members.

14. The combination with a bottle head havingan anchorage ledge and a rounded top, of a closing cap comprising legs to engage said ledge, a cover part to close the bottle mouth, and llat spring arms on the cover attached to the legs at an angle and adapted to spread said angle as the cap is pushed on the head to engage the legs on said ledge, and to be further depressed on the bead and spread the said angle still further and release the legs, substantially as described.

15. The combination with a rounded bottle head having an anchorage ledge, of a closleg cap thereon "sprung out of normal posi- 5 tmn and exertin a se the bottle moutfi by engagement with said ledge, the enge ing part of the cap having a sharper curve t an the head and adapted to be further spread to release the engagement by pressing the said part further down on the head, substantially as described.

In testimony whereof I have hereunder induced pressure on signed my name in the presence ef the sub- 10 scribed witnesses.
